During the Kirill wind storm on 14th of January 2007 I have lost my gears for Elevation and Azimuth. After couple weeks I got all parts and can to start repairing of whole system. This page show how is developed and done first moving part of system. Moving Crew was produced by TECHNOMETRA Radotín CZ, which produce also mechanical systems for Boeing Airplanes. Only this factory has in my region so big machinery and very detail workers. Click on picture increase the size of picture. |

Drum and main axe, which will be install below the dish. Expected element for moving is iron 8mm rope. More details will follow. | |
Test after installation. I have calculated force around 8ton for loading. For this force test I had installed iron rope 4mm diameter and tested moving up. After couple seconds was iron rope damaged. According the table, the 4mm rope is tested for 4 tons. Expected moving force is there and with drum can be expected torque moment better like 12.000Nm. | |
